TLDR
The calcium content of blood serum can be accurately determined on 0.1-0.25 ml samples by atomic absorption measurements in an air-acetylene flame after removal of the proteins by coagulation and centrifuging.About:

Osteopontin-hydroxyapatite interactions in vitro: inhibition of hydroxyapatite formation and growth in a gelatin-gel.
TL;DR: In this system, osteopontin, distinct from other phosphoproteins which both promote and inhibit hydroxyapatite deposition, did not enhance mineral formation at any concentration tested.

Determination of Calcium in Urine and Serum by Atomic Absorption Spectrophotometry (AAS)
TL;DR: The determination of calcium in biologic fluids by atomic absorption spectrophotometry is interfered with by the presence of protein, cations, and those anions that form complexes with calcium, but was overcome when lanthanum was included in a 1:50 dilution of serum or urine.

Fourier transform infrared spectroscopy of the solution-mediated conversion of amorphous calcium phosphate to hydroxyapatite: New correlations between X-ray diffraction and infrared data
TL;DR: It is suggested that a combination of second-derivative and curve-fitting analysis of the ν1, ν3 phosphate contour allows the most reproducible evaluation of these spectra.

TL;DR: The hypotheses that the interaction of OPN with HA is determined by the extent of protein phosphorylation and that this interaction regulates the mineralization process are tested are tested.

An atomic-absorption spectrophotometer and its application to the analysis of solutions
TL;DR: In this paper, the construction of an atomic absorption spectrophotometer is described and its performance is illustrated by results obtained in applying the instrument to the analysis of solutions, and the results confirm that the sensitivity of the absorption method is independent of the excitation potential of the spectral line used.
